Measure fNIRS in high-density set-ups, from anywhere on the head, concurrently with (nearly) any other modality. Monitor your subjects via Wi-Fi while direct-to-device system recording ensures data is always stored, or choose higher-bandwidth USB connectivity for applications in BCI and neurofeedback research paradigms that require ultra-high performance processing.

Aurora fNIRS Recording Software

The NIRSport 2 comes together with Aurora fNIRS: a new software platform designed to maximize user-friendliness, flexibility and intuitive workflow.

In just a few clicks, Aurora fNIRS allows you to set-up a complete experimental configuration. The automated signal optimization algorithm ensures optimal signal quality before a measurement is started. Once data is being recorded, HbO and Hb concentration changes can be visualized in real-time in several display modes. In addition, high-end whole-head visualizations are immediately available.

Aurora fNIRS is developed exclusively for the NIRx NIRSport 2. Learn more about Aurora fNIRS.

German Engineered to Meet the Most Demanding Research Requirements

The back of the NIRSport 2 with USB mini port for hard-line data collection for high-bandwidth, rapid-sampling requirements (e.g., BCI, neurofeedback). The battery may be wall-powered during recording and LED indicators give visual feedback on battery levels on the system itself for computer-free measurements (battery levels are also shown in the recording software for hard-line or wireless recording using the Aurora fNIRS software).

Side 1 of the NIRSport 2 shows the heat-dissipation (“head sink) bottom metal plate, which allows for maximizing the source and detector power and sustained performance, even in very warm outdoor conditions.

Side 2 of the NIRSport 2 shows one of its heat-dissipation vents (additional vent on bottom) which further improves system performance.

NIRSport Tandem-Cascading

The NIRSport 2 may be ‘daisy chained’ to connect multiple systems together in tandem-cascading configuration. 2, 3 or 4 systems may interconnect in tandem-cascading mode; in each case, all data and event trigger information is fully-synchronized between NIRSport 2 devices.

For example, in a dual-tandem configuration, detectors from system 1 are reading light from sources in both system 1 and system 2. Likewise, detectors from system 2 are reading light from sources in both system 1 and system 2 as well. This allows research teams to easily expand their studies by combining NIRSport 2 instruments to measure either:

larger brain regions of interest

higher-density configurations

hyperscanning (multi-subject) fNIRS measurements

Event triggers may be sent wirelessly or hard-lined through the trigger port (parallel port adapter included - option to use BNC spitter input) directly to the NIRSport system.

The back of NIRSport 2 with cascading ports (extension A and B) to link multiple NIRSport amplifiers together for extending source/detector number and channel count.

Example of NIRSport 2 + EEG Data Integration

Data integration with NIRSport 2 and EEG systems is easy with event synchronization. This may be done at the start and end of experiments, during 'trigger' events, or arbitrarily during the experiment.

Example Right: The event trigger generated by the presentation computer is sent to the digital interface (trigger splitter), where the events are then sent to the NIRx trigger splitter box, splitting each trigger and maintaining the proper voltage, sending the even signal to the NIRS and EEG systems. This trigger-splitting method may be used from different input devices (e.g., TMS, eye-tracking, etc.), and sent to multiple recording devices.

NIRx fNIRS Application Overview

NIRSport 2 with back strap for mobile applications: the system weighs only ~800g. Keeping the amplifier on the back, rather than mounting it to the head cap, leaves the head and neck free to move in a naturalistic way.
